Final answer:
To calculate the total amount from a transaction that includes sales tax and tip, apply a 4% sales tax to the transaction amount and then add a 20% tip on the original amount. An example with a $100 transaction results in a total of $124 paid, including $4 in sales tax and a $20 tip. When assessing financial outcomes in games, it's crucial to understand the odds and payout structures to predict expectations of gain or loss.
Step-by-step explanation:
The question revolves around calculating commissions, sales tax, tip, and evaluating financial outcomes in certain scenarios. To compute a total amount paid including sales tax and tip, you would take the original transaction amount, add on 4% of this value as sales tax, and then add a 20% tip based on the initial amount.
For example, if you had a transaction of $100, the sales tax would be $4 (4% of $100), and the tip would be $20 (20% of $100). The total amount paid would therefore be $124.
In a scenario regarding the long run financial gain or loss when playing a game, one should assess expectations based on the known odds or potential payout structure of the game. It's important to consider these variables when determining whether you'd expect to end up ahead, behind, or at a break-even point.
